Pretty unstable app. I would NOT buy it after 3-day usage experience. I am pretty sure there are better (and free) alternatives.

iStumbler pricing is too aggressive, leaving iStumbler naked to be copied and raped commercially by bottom feeders like Koingo Soft (AirRadar). I bought a license in solidarity (iStumbler is great software) but as most of my machines are on Snow Leopard, I'm still mainly using the free version and didn't have to. Zero to $25 is obnoxious. If being obnoxious was your goal, you've succeeded. In the long term, encouraging competition is not good business practice. My new lower review is based on the $25 price tag. The software still works fine. I hope the developer finds a better compromise between thinking about his users and thinking about himself. $20 was still okay for a simple but nifty utility which works on all your computers.

Alright folks, help me out here. If all I’m really wanting is something to help deconflict from other Wi-Fi networks in the area, wouldn’t Apple’s included Wireless Diagnostics tool work just fine? And save me 25 bucks to boot now that the iStumbler developer has decided to start charging to put a pretty wrapper on something Apple already provides for free? Before I get flamed, of course I know iStumbler does other things but I’m just interested in identifying the local Wi-Fi networks and their channels. Do a spotlight search on “Wireless Diagnostics” and open it up. Click on “Scan Now” in the lower right and voila, Apple’s cool little app finds all the 2.4 and 5GHz networks within range and the first column on the left makes suggestions on the 2.4 GHz and 5 GHz channels which are least used (Best choices if you don’t want to let Apple automatically select an appropriate channel). Plus if you pull down the Wireless Diagnostics “Window” menu, there’s other cool things in the app’s toolbox like a sniffer function.

Thanks Alf for the great software. I've been using this for many years to help diagnose WiFi issues and it's always been solid. Thrilled to pay $25 for this update that has saved me many more hours and $$$ in the past. Keep up the great work and don't let the haters get to you!!

Meh. Last time I tried any of these programs they only worked with the built in Mac adapters. If you are not afraid of the terminal, you can do a little grep foo, or better yet install aircrack-ng suite, and get more data.

When the app was free, I would use that since it was the best free app out there. When the dev started charging, I considered it but found others that cost less and did just as many things as I needed. Is the app good? Yes. But is the App worth the current price when there are others out there with the same capabilities or more for less? No. At $10–$15 I would have stuck with it, but not at the current price. I think the dev should have looked at what competitors where charging for equivalent features and priced accordingly to retain customers. And just to be clear: I do believe in supporting good apps by paying for them, even if they are donation-ware. I buy shareware regularly, and recommend apps that I see as worth the price. In this case, it’s not worth the current price, and is an otherwise average app in an already crowded field.

I highly recommend NetSpot or WiFi Explorer. iStumbler is nice but not worth $20. Note to developer: when you raise the price, try adding significant new functionality so there is an obvious reason for the price increase. Your utility is now among the most expensive of its kind. so it should provide the most features of its kind.

The feedback on this page should serve as a warning to any developer who wants to start charging for an app they previously offered for free. Many people are ungrateful and think, though they get paid for their work, you have no right to do the same. One may quibble over the price, but the principle remains. I've seen complaints when an app went from free to just $5. You may think you can do without such people as customers, but they will frag you on websites like this one anyway. They seem to miss the irony that they are being every bit as mean spirited as they accuse you of being. It's a clear case of transference. They think they'll look better by ragging on you. They're wrong. If an app worked well enough to get a four star rating when it was free, it's utility doesn't drop significantly if it now costs a little or a lot. Cheap and expensive are subjective values at best, having nothing to do with how well an app works. Thus, without even trying it, I'll give it four stars based on the majority of reviewers who like it.

The worst!!!! The money squeezing Developer wants $20 to strengthen his coffers. Don't give to him. Get NetSpot which is free (as in Beer) and enjoy a great application.If you have an old edition of iStumbler it is still good,unfortunately for him he can't take it away from us. It is available for SnowLeopard and Leopard but if you don't have it just use NetSpot.

No longer free - dev's web page states clearly it is now $20 for all the computers you own. Seriously? $20? I would have considered paying $2 for this useful utility, but $20 is way too much. It's a good app but plenty of good alternatives out there - check out wifi explorer (my reccommendation); other apps besides these. Radar

Fun and useful, but when I tried to uninstall it, it left shards in the Security and Privacy control panel under Locations that I can't figure out how to get rid of. Therefore it gets a low rating from me. 10.8.2 iMac

OS X Lion has a built-in utility for testing WiFi networks, Wi-Fi Diagnostics Utility, which can be found in the /System/Library/CoreServices/ folder (as explained in a MacFixIt article: http://reviews.cnet.com/8301-13727_7-57346631-263/diagnosing-and-addressing-wi-fi-signal-quality-problems/).

I love this app, however on Lion it crashes shortly after start. Hunting around, there are betas available here... http://istumbler.net/beta/ the author is still developing this, yay! Running the latest beta and enabling bluetooth seems to cure the crashes. I look forward to a final version where active bluetooth isn't required but for now I'm happy enough!

After upgrading to 10.7.1, iStumbler crashes regularly on my MacBook Air, but it doesn't crash on my iMac. No crashes on either machine under the initial 10.7 Lion. Update notes for 10.7.1 does say something about improvements to WiFi, so I'm wondering if the associated changes may be affecting iStumbler?

Works a treat. After comparing it to the rest of the commercial spyware/trojans in this category, thank goodness for iStumbler. I don't know why Apple doesn't give us info on what channels are in use but iStumbler let me pick an empty channel for use on my LinkSys WTR54GL (you have to specify the channel, there's no auto) and get online. On my way to donate right now.
